The cross-sectional area of a wide- flanged W16x15 beam has the dimensions shown. a. Obtain a close approximation to the handbook values of Ix =657 in.4 and Iy=37.2 in4 by treating the sectionas composed of three rectangles. b. If a built-up section is then created by welding two W16x15 sections, one atop of the other, what would be the Ix about the centroidal x-axis?

Beams

In structural engineering, a beam is a component made of a variety of materials (including steel alloys, and wood) that can resist loads applied laterally to the beam axis. Members, elements, rafters, shafts, and purlins are all terms used to describe beams.
